At least 18 people people died and several others went missing as incessant heavy rainfall triggered multiple landslides across the Darjeeling hills on Saturday, sweeping away homes, damaging roads, and cutting off several remote hamlets, officials said.
Furthermore, due to the excessive rainfall, an iron bridge also collapsed.
The Dhudia bridge, which is an iron bridge over the Balason River at Dudhia, connecting Siliguri and Mirik, was damaged and collapsed due to the heavy rainfall in the region.
Rescue and relief operations are underway by the local administration, police, and disaster response teams, Darjeeling Sub-Divisional Officer (SDO) Richard Lepcha told PTI.
The National Disaster Response Force (NDRF) has joined the rescue operations in Mirik Lake area, one of the worst-hit zones, officials said.
Chief Minister Mamata Banerjee announced compensation for the victims without specifying the amount and said she would visit north Bengal on October 6 to assess the situation in the region where a large number of tourists have also been affected.
Prime Minister Narendra Modi has said he is "deeply pained" by the loss of lives in Darjeeling. "We are committed to providing all possible assistance to those affected," he said on X.
In a post on X, PM Modi said: "The situation in Darjeeling and surrounding areas is being closely monitored in the wake of heavy rains and landslides."
Speaking to TV9 Bangla news channel over the phone, Mamata Banerjee described the situation as "grave".
"Due to incessant rain in Bhutan, the water has overflowed into North Bengal. This disaster is unfortunate - natural calamities are beyond our control. We are deeply saddened. I held virtual meetings with officials of five affected districts along with the chief secretary. I have been monitoring the situation since 6 am," she said.
The chief minister said she would leave for North Bengal on Monday afternoon, accompanied by Chief Secretary Manoj Pant and monitor the situation from Siliguri.
She had decided to go there after the conclusion of the Durga Puja Carnival in Kolkata on Sunday, in which over 100 puja committees will take part.
According to Banerjee, more than 300 millimetres of rainfall occurred in just 12 hours, causing severe flooding and landslides across at least seven locations. She compared the situation to the intense flooding that Kolkata experienced last month during the festive season.
"There has been continuous, heavy rain for 12 hours. Landslides have occurred at seven locations. I am keeping a close watch and hope to reach by around 3 pm on Monday," she said.
Thousands of tourists have been stranded across the region due to the landslides and road blockages. The CM assured them that the state government would make arrangements to bring them back safely and appealed to tourists not to panic or rush to leave.
"Many tourists are stranded. I request them not to hurry. Please stay where you are. Hotels must not overcharge them. Their safety is our responsibility, and the administration will ensure that," she said.
Banerjee also announced that the families of those killed in the disaster would receive government compensation and employment for one of their members, though she did not specify the amount.
According to reports compiled by the NDRF and the district administration, 10 deaths have been confirmed so far, while two others remain untraced.
Fatalities were reported from several locations - Sarsaly, Jasbirgaon, Mirik Basti, Dhar Gaon (Mechi), and Mirik Lake area. At least four people were rescued from the debris in Dhar Gaon, where heavy mudslides flattened several houses.
The landslides disrupted traffic movement on key routes including the Mirik-Sukhiapokhri road, while communication lines to several hilltop settlements were snapped.
North Bengal Development Minister Udayan Guha described the situation as "alarming" and pegged the death toll at seventeen citing reports.
"The loss of lives is tragic. As per our reports eleven people have died in Mirik and six in Darjeeling. But the figure is not yet confirmed," Guha told PTI.
To prevent any untoward incident, the Gorkhaland Territorial Administration has decided to shut tourist spots in Darjeeling, including the Tiger Hill and Rock Garden. The toy train services have also been suspended.
Authorities have asked residents and tourists to be careful and keep themselves updated on road and weather conditions. Bengal police set up a hotline for stranded tourists and residents: 9147889078
A senior police officer said heavy and continuous rain has severely hampered rescue operations.
"The terrain is slippery, and several houses have been damaged. The extent of damage is still being assessed. Earthmovers are finding it extremely difficult to operate on these slopes," he said.
Several families in Bishnulal Gaon, Ward 3 Lake Side, and Jasbir Gaon in Mirik have been shifted to safer places as precautionary measures, while temporary relief camps have been set up in coordination with local NGOs and the district administration.
The India Meteorological Department (IMD) has issued a red alert for extremely heavy rainfall in sub-Himalayan West Bengal, including Darjeeling and Kalimpong, till October 6, warning of more landslides and road blockages due to saturated soil conditions.
Officials said the priority remains to trace the two missing persons near Mirik Lake and restore connectivity to cut-off regions as rescue operations continue through the night under challenging conditions.
